Kalanchoe named Pueblo

ABSTRACT

A new and distinct variety of kalanchoe plant particularly distinguished by its unique orange-yellow flowers supported by rigid upright stems in tightly clustered panicles above and between shiny dark green leaves. This plant is intended for year-around four and six inch pot production and has a ten to twelve week flowering response to photoperiod control. It has a rapid and vigorous growth habit with caespitose branching, abundant foliage, and a profuse production of flowers.

BACKGROUND OF THE NEW PLANT

My new variety of kalanchoe plant originated as a seedling resulting from breeding efforts carried on by me at Cartago, Costa Rica, with the object of producing new and better varieties for the kalanchoe market. The geneology of this new plant is as follows: ##STR1##

The seeds of this mating were collected in February 1977 and sown in June 1977. The selection of this plant for propagation was made on Jan. 4, 1978, and first propagation was done by me with cuttings of the selected plant on Jan. 23, 1978, in Cartago, Costa Rica. Subsequent propagation through successive generations has shown that the novel characteristics of this new variety hold true from generation to generation and appear to be firmly fixed. This new kalanchoe variety is now being propagated by cuttings at West Chicago, Ill., and at Parrish, Fla.

DESCRIPTION OF THE DRAWINGS

My new kalanchoe cultivar is illustrated by the accompanying drawings, of which sheet 1 is a full color photographic print showing the growth and flower display characteristics of the plant, and sheet 2 is a print of a close-up photograph of the flowers of this plant which has been hand-painted to show the true color of the flowers as specified.

This kalanchoe variety is quite unique in character and is particularly distinguished by its orange-yellow flowers displayed in closely massed panicles supported by rigid caespitose stems above the dark green shiny leaves. This new kalanchoe cultivar is particularly adapted for year-around four and six inch pot production under photoperiod control and has a substantially uniform ten to twelve week flowering response. The new plant has a vigorous, upright and rapid growth habit with abundant foliage and a profuse production of flowers which have a four to six week lasting quality on the blooming plant. 

I claim:
 1. A new and distinct variety of kalanchoe plant, substantially as herein shown and described, characterized by its orange-yellow flowers displayed in panicles supported by rigid stems and clustered above and between dark green shiny leaves, the plant having a strong, vigorous and rapid growth habit and a profuse production of flowers.
